Measurement of a voltage response caused by a current excitation signal sent to a biological system under study, i.e. measurement of electrical bioimpedance, is typically using analog or digital lock-in detection. Such a detector consists multiplying

The central aortic pressure (CAP) is traditionally measured using a pressure sensor inserted into aorta. This invasive procedure is costly and can lead to complications. Therefore, attention is paid to the development of non-invasive methods. Tonomet
